Well, after a couple hours reading stuff over here, trying unsuccessfully all the solutions, also found this article that i thought it would save my life... nothing.
Long story short.
Here is my View (all combinations)
@Html.DropDownList("yearDropDown",(IEnumerable<SelectListItem>)ViewBag.yearDropDown)
@Html.DropDownList("yearDropDownxxx",(IEnumerable<SelectListItem>)ViewBag.yearDropDown)
@Html.DropDownList("yearDropDown",(<SelectList>)ViewBag.yearDropDown)
@Html.DropDownList("yearDropDown")
Here is my Controller
public ActionResult(int year)
{
var years = new int[] { 2007, 2008, 2009, 2010, 2011, 2012 }
.Select(x => new SelectListItem {
Text = x.ToString(),
Value = x.ToString(),
Selected=x==year }).Distinct().ToList();
years.Insert(0, new SelectListItem { Value = null, Text = "ALL YEARS" });
ViewBag.yearDropDown = new SelectList(years, "Value", "Text", years.Where(x => x.Selected).FirstOrDefault());
return View();
}
Here is my rendered HTML. Selected nowhere to be found.
<select id="yearDropDown" name="yearDropDown"><option value="">ALL YEARS</option>
<option value="2007">2007</option>
<option value="2008">2008</option>
<option value="2009">2009</option>
<option value="2010">2010</option>
<option value="2011">2011</option>
<option value="2012">2012</option>
</select>
Needless to mention, but i will, i checked in my Watch and SelectList actually has SelectedValue property populated with the selected year passed to the controller. But when i renders at the view, it goes to the first option.
Please, I need the solution for DropDownList
, NOT for DropDownListFor
. I am highlighting this because i saw other people here asking for the same help and bunch of people gave them instructions, and almost order them, to use DropDownListFor. There is a reason why i NEED to use DropDownList.
SOLUTION: Look at my own answer. However, here are the simple changes i made.
Controller:
ViewBag.yearDropDown = years;
View:
@Html.DropDownList("yearDropDown")
The problem may also be the name, see here.
In the Controller
ViewBag.PersonList= new SelectList(db.Person, "Id", "Name", p.PersonId);
In the View
@Html.DropDownList("PersonList",(SelectList)ViewBag.PersonList )
This will not work, you have to change the name, so it's not the same.
@Html.DropDownList("PersonList123",(SelectList)ViewBag.PersonList )
So change yearDropDown and it Will Work for you.
